Prologo Nago R4 PAS Tirox 137 saddle

The NAGO R4 PAS (Redesign 4) is the evolution of the iconic NAGO, the Prologo saddle born in 2008 that has already won a Giro d'Italia and numerous Classics over the years. Designed from the needs of professional teams supported by Prologo, the new saddle has been perfected through "Pressure Map MyOwn" testing to meet the needs of all cyclists seeking maximum performance and comfort even for long rides.

Compact dimensions with a length of 245 mm and T-shape shape, with a slightly forward anatomical center, to provide good freedom of movement in the saddle and maximize pedaling efficiency in all positions. The semi-round ergonomic shape also makes the new NAGO R4 PAS ideal for cyclists with average flexibility in terms of pelvic rotation.

The semi round ergonomic shape also makes the NAGO R4 PAS ideal for cyclists with medium flexibility in terms of pelvic rotation, while the narrow width of only 137 mm fits people with not too much ischial bone width.

The open NAGO R4 PAS version, features two separate fully independent sections, made of the latest generation of variable density foams, to ensure excellent support and comfort during all phases of pedaling. At the center is Prologo's PAS system: a wide central channel and a perforated base to eliminate pressure peaks even during maximum pedal thrust phases.

The base is made of long-fiber carbon, a material that offers an excellent compromise between stiffness and comfort. Rail TiroX made of light-alloy steel, a material with an excellent balance between weight and strength, which gives the saddle lower stiffness and superior vibration absorption, for those seeking greater comfort.
